Abstract: An aqueous primer composition comprising a condensation polymer available on condensation of a copolymer composed predominantly of a cationic monomer, an alkoxysilane monomer and an ethylenically unsaturated monomer with a specific alkoxysilane.  For this reason, regardless of the alkalinity of the substrate, the aqueous primer composition can form a highly water-resistant, alkali-resistant, tough film.  Moreover, when forming a film thereby and forming a finish layer thereon, this composition shows a high affinity for the top coating or adhesive to insure a firm integration of the finish layer with the substrate surface.

Abstract: A steering assembly (10) for use in turning steerable vehicle wheels includes a rack (12) and a pinion (14).  A yoke (28) is continuously pressed against the rack (12) by a yoke spring (32).  The yoke (28) has a stem (62) which extends through an opening (64) in a housing (16).  During construction of the steering assembly (10), a desired range of transverse movement between the rack (112) and the pinion (14) is obtained by applying force (114) to the rack to position the rack at a first end of the range of transverse movement.  The direction of the force applied to the rack (12) is then reversed and the rack and yoke (28) are moved together away from the reference position until the yoke stem (62) has moved through the desired range of transverse movement.  A yoke plug (20) is then fixed against movement relative to a main housing section (18). After the rack and pinion steering assembly (10) has been constructed, it may be desired to check the range of transverse movement between the rack (12) and pinion (14). The distance between opposite ends of the range of transverse movement is determined by determining the distance through which the stem (62) on the yoke (28) moves relative to the housing (16).

Title: Computer system having client-server architecture
Inventor: IRELAND PAUL STUART
IPC: G06F9/50
Filed: 1995-07-19
Granted: 2000-01-11
Abstract: A network manager for a telecommunications network has a client-server architecture. The software components of the network manager include a set of clients (50) which form part of the application programs of the network manager, a user interface (32), a database (36) containing details of the network and a communications stack (38) for communicating with exchanges managed by the network manager. The clients (50) generate requests to run jobs on servers (52) and (54). The jobs which are run on server (52) are eventually destined for a resource in the form of a database (36), while the jobs which are run on servers (54) are eventually destined for resources in the form of exchanges. The requests are initially passed to software module JBM. This module then checks if the resource for which the job is destined is free and, if not, puts the job on a holding queue. If the resource is free, it checks whether the job is scheduled for immediate execution or execution at a future time. If it is scheduled for execution at a future time, it is put on a queue of scheduled jobs. If the job is scheduled for immediate execution, the module JBM checks if a server is free to accept the job. If no server is free, the job is put on a queue of jobs awaiting immediate execution. If the server is free, the module JBM instructs a module SMAN to load the job onto the free server.

Granted: 2005-08-23
Abstract: A horizontal miss distance filter system (220) is provided for inhibiting resolution alert messages from an air traffic alert and collision avoidance system (210) to a pilot's display (230). The horizontal miss distance filter employs a parabolic range tracker (10) to derive a range acceleration estimate (11) utilized to discriminate intruder aircraft (110) having non-zero horizontal miss distances. The horizontal miss distance calculated from the range data provided by the parabolic range tracker is compared with a bearing based horizontal miss distance provided by a bearing based tracker (22). The smaller of the two calculated horizontal miss distances defines a projected horizontal miss distance which is compared with a threshold value. Any resolution alert for intruder aircraft whose projected horizontal miss distance is greater than the threshold will be inhibited unless it is determined that the encounter involves a maneuver of one of the aircraft. As many as five maneuver detectors (50, 52, 56, 58 and 64) may be employed to assess whether the encounter involves a maneuver. If any of the maneuver detectors establish the occurrence of a maneuver, then a resolution alert provided from the TCAS system (210) will not be inhibited.

Abstract: A device for regulating sound level of audio systems and noise level of machinery as a function of the desired human auditory level. In the case of audio systems, the produced sound from the speakers is collected by a microphone and measured by a sound level meter in decibels and converted to electrical signal and by the use of a computation process of a computer, the electrical signal is then sent to the damper selector switch which averages the signal value over periods of time and sends the stabilized signal to the comparator unit. The desired human auditory level is selected on the sound level selector switch which generates a proportional signal and send it to the comparator as a reference level. The comparator compares the signal received from the damper selector switch to the reference line generated by the signal from the sound level selector switch. If the signal value from the damper selector switch is higher than the signal value from the sound level selector switch, the comparator sends a signal to decrease the volume control until the signal from the damper selector switch is equal to the signal from the sound level selector switch. If the signal value from the damper selector switch is lower than the signal value from the sound level selector switch, the comparator sends a signal to increase the volume control at a much slower rate than decreasing it until the damper signal is equal to the sound level selector switch. If the signal value from the damper selector switch is equal to the signal value of the sound level selector switch then the signal is disabled. In the case of machinery circuit it is similar to the audio system circuit with minor differences.
